sorry guys I just bought a new saito fg30 to cure this problem
(found it on ebay still on the box bagged of someone who gave up to a big project paid under$500 , so the st3250 converted+the cmpro edge+ a crrc pro 26i+an other cmpro edge 540 frame will be on ebay soon to pay for this one ,funny enough the petrol saito don't use needle bearings on the conrod, could someone explain this to me!! the other problem Im facing with this engine is because the carb is on the back ,[link]http://www.macgregor.co.uk/saito/fg30.htm[/link] the engine will be way foward, so two choices using a normal plastic mount, so I can slide the engine back and cut a hole for the carburator,in the firewall, doing this I cant use the nice supplied alloy mount which they say it helps cooling, or cut the firewall completly and re glue it an inch 1/2 back, I migh post few pictures so You can help me to decide .
Cheers
Luis
