Hi Glen,
First of all welcome to our club and forum..
The GV brand of cars is distributed in Australia by Model Engines
www.modelengines.com.au
I couldn't find any instruction manuals with your particular engine, however the US distributor of Force engines (OFNA), had an instruction manual on their website
www.ofna.com/pdf/eng-force12s,15s.pdf
Just a few tips for tuning the engine..
- Always make sure it is blowing a nice trail of smoke from the exhaust..too rich is better than too lean.
- You will never get a perfect tune by any settings in a guide, these settings are designed to get the engine started ready to tune.
- Your most welcome to bring your car down on one of our race days, (next one is this Sunday 1st July) we can give you some pointers on how to tune the engine, and have a chat to our club members about what you may need for racing such as tyres and spares etc..
Good luck and hopefully see you at the track..
Cheers,
Craig
