Hi everyone, i present to you my conversion in progress of an echo srm200db brushcutter engine which is 21cc.
The magnetic plate has been replaced by an rcexcl electronic ignition with actually 30° of advance setting, the original WA59 carburetor was replaced by a slightly larger WT93A.
I now have to replace the ugly original exhaust which is too heavy and too restrictive.
And find the right carburetor settings because I hope to run this engine on E85.
For now, the weight is around 1.2kg, and i hope to be able to turn a 16x6 propeller at around 8000rpm.
