I just finished rebuilding my 800cc SOHC f8b and boy did I wake this little engine up with port, polish , exhaust, cam and valves! I’ve richened up my stock carb about as far as it will go and still seems to be running on the lean side especially under hard acceleration. I’ve read some posts and going to try my hands at a weber 32/36 two questions:
1- Is this the best upgrade carb for the engine?
2- Will it fit with stock manifold? I ordered the Suzuki Samuri conversion kit with carb...
After operating, the first several inches of the exhaust pipe where it leaves the engine on my Hisun 400cc glows bright red. Is this normal? There are various heat shields and other insulating material along the pipe’s pathway, so I’m guessing it is. Also, there are no other signs that the engine is running hot.
I am working on a friends hisun 800. he said whenever you transport it on a trailer it takes forever to start and he has to floor it to get it to start. he also said it wouldn't go over 30mph like it was being held back. I get it to my house try to start it and all im getting is backfire through intake. I checked spark it was good. I know its a no no but I sprayed a small shot of starting fluid in airbox to see if it would start and it backfired and lit the fluid on fire. currently I am wondering if the valves may be out of adjustment anybody have any suggestions or help would be greatly appreciated.
