The Adapter plate is a 1/2" thick and is custom machined out of 6061 Aluminum to convert the small four hole bolt pattern 58 mm or 2.283" ( on engines like the Robin EH025 and the Honda GX25 and others) to the large 70.7 mm or 2.783" four hole bolt pattern found on the Robin EH035, Honda GX35, Tanaka PF-4000 and others.
This adapter will allow you to use the smaller four hole bolt pattern to attach it to many of our gearboxes.
You will also need to get the rest of the parts in order to install on the engine that are not included.
Use the search on the web site to find the rest of the parts.
Notice the adapter changes the location of the engine so keep tat in mind when mounting.
Two Cycle engines will run in any position along with the Honda GX22 and GX25.
The EH025 can run at a 30 degree angle 100% or about 20 mins in any position.
See your Robin Subaru engine manual for more details.
Engines like a Honda GX22, GX25, Robin Subaru EH025, Mitsubishi 22.6 cc and some others with the same size of clutch rotor and engine face mounting pattern.
