plz help me make a petrol engine for rc car and other engines??
 

There are quite a few sites devoted to model aircraft and car engines. Here are two of my favorites:

RC Universe features rc cars, rc airplanes, rc helicopters, rc electric planes, rc boats, radio control jets, rc discussion forums, rc classifieds and auctions.
RCGroups.com: The ABCs of Radio Control - Aircraft, Boats, and Cars!

Both sites are very good. RC Universe has numerous forums devoted to engine development. In order to save putting many irrelevant links here, can you tell us a little more about what you want to do?

Are you asking about making an engine from scratch? That can and has been done, but it is very difficult and requires significant machining ability and equipment. On the other hand, if you are talking about converting a grass trimmer or similar 2-cycle engine to model use, that is quite easy and can be done with little more than a hacksaw and file.

There are even threads specialized to discussing homebuilt ignitions and running petrol (gasoline) engines on mixtures of gasoline and methanol without an ignition.

I would be delighted to give you more links, once I understand what you are are seeking to do.

Basically, the engines you are talking about probably have carburetors with throttle arms. One simply connects a model servo to the throttle arm.

If you happen to have a very old engine that does not have a throttle arm on the carburetor, you can control its speed, albeit less effectively, by using a flutter valve in the exhaust port. It is highly unlikely you will have that type of engine unless it is an antique.
