Hi Phil
Have rebuilt many two stroke and four stroke engines over the years its not hard just follow the specifications exactly when rebuilding ,one of the most important things make sure everything is spotlessly clean slightest bit of grime will destroy your work .
l finished the rear wing mounts they are all bolted on ready for painting ,l also put the Z bracing in between them it has really stiffen up that weak area.
Have you got a price on the engine set up from Tom.
cheers Geoff.
