How to install Cox Muffler?

Well, that was confusing. So why is it that the top is to be with the flange up if using a starter spring, and down if not? I am not understanding why.

I do believe it is to allow clearance if the Starter Spring to wrap around the bottom of the cylinder? ??
Re-read the first paragraph, Flange down with spring, flange up without spring.

Sound like u nead the professionnel advice y use al of them and it wil Not fit on al .049 on the bee engine al of them wil fit wit cars engine just the old cox smaler one fit only the gtp wil fit wit nead modification To the crank. Pul starter plastiques fixation


cars engine the larger exaust nead larger exit larger hole and if u want To use on black widow golden bee Venom al engine wit spi wil lost power rpm may run longer du To lower rpm  the texaco wit larger ventury like the black widow tank ventury size wil gain power using the gtp exaust collector wit smal .7 pipe texaco dont use spi sur start cylinder Good performance upgrades for exaust if use black widow type cylinder best change for non spi cylinder gtp exaust collector work bether just wil not change sound mutch like wit the larger one gtp exaust nead pipe To work for sound its very Noisy straight pipe wit just tube To direct exaust gtp exaust collector work wit the egr valve sistem

If use the gtp exaust collector. Nead its ground cylinder To fit without modification To the parts the cylinder wil Not Screw to the bottom  and left the  spi close wit big lost in compression its posible To modify glow plug for extra compression exept witout large pipe for back presure wil Not work and lost performance it only work wit very large ventury extra compression plus tuned pipe and after al litle modification engine just back To its normal power mabe litle extra rpm wit Nice sound y tink for the golden bee best its use the large exaust new from cox dril two new hole enlarge the one alredy there two hole on the side wit one in the Front pointing the prop just dont dril To large try smaler first them enlarge after test m'y self Not using the spi in Most of m'y tuned modified engines simple change cylinder for non spi use normal glow plug
Some engine exaust port point direct To the Front som point on difrent angle  and To use the gtp exaust work wit the exaust opening point direct To the collector exit so its Not so simple To ad exaust To engine Not desing for it wy Not just use engine made for it like qz ez bee engine ???  just y tink cars parts work bether for cars At least If know about  how tune pipe work bether Not change Good performance engine Only a good experienced mechanic wil have Good result its big To complexe To explique its hard long  To traduction from french y dont have mutch time sory best Not use cars parts for plane y have made lots of test wit tee dee and multiple Reed valve engines gtp exaust collector its  Not Bolt on u need the machine To make the Bolt on To fit the cox exaust make sur To fit befor dril new hole To align the large cox exaust work bether for sound supresing but the best for plane stay the quiet zone engine for Reed valve engines its spring trap wit tube work best y tink its bether desing for plane the gtp exaust collector work wit tee dee engine exept lots of custom mod To fit hope it help Answer question ?

Yes hard To under stand y no y no just take time read as is translation wont help

Tube on the egr valve gtp collector place on top never revers the cox exaust fit wit the hex down Not on the top in fact if Not fit its because the hexagon size to big use file angle grinder dremel tool To take Of the material nead To fit on aluminium 8cc tank it need the one wit larger plastiques reed valve retaner chim Not the paper gasket wit Reed clip retaner its To tight wit crankcase and tank  dont try chim fuel tank wil result damage To crankchaft piston rod Most new parts wil fit wit new engine wit plastiques back plate older engine need fit test lots litle adjustment To fit correct new parts take time To instal the parts carfuly remove cylinder just exemple of the gtp egr valve type exaust collector Not silencer it self its manifold for exaust sistem look how it work wit valve the tuned pipe behind the valve

The valve type collector work bether on cars for plane just use normal exaust keap gtp parts for boat cars or plane using smal cowl wit nead To redirection of exaust fume
