Os makes a real nice .18. what crank type do you need sg type, short crank or long crank, rotary carb or slide the .18 cvrx line is a great drop in replacement and aint bad priced either...
slide carb version http://www.osengines.com/engines-car/osmg2102/index.html
Do you need new exhaust? Will the motor mounts hook up to it? Will the rotostart work on it as well? Just trying to gauge what kind of project i am in for. Thank you for the response!
got a pic of your existing engine, then I may be able to help a bit more, the OS uses a side exhaust so I think is the same, should not take many mods to get done tho, I have done far more complex ones without trouble and I am sure you can make it work....
