It is a Webra P5-91i. Runs around half an ounce a minute in gas. So far has been a good engine with plenty of power for the plane. The plane bounced right on the money with this engine. I do not have an all up weight yet.

many people would initially think this would be ''too much'' for this plane. but look at this balance. balances right on the money with a larger engine.
I present this question to the group. why balance using dead weight? why not install the necessary weight in the form of a larger power plant.
warning. this line of thinking may lead to fun.
You have a throttle on the engine, so you can throttle it back as needed. If the plane is balancing out OK, then go for it. Using a larger and heavier engine seems to be better than having to add a lot of lead weight to get the CG out. At least the extra weight is useful.
Earl , Well said. especially on gasoline and 4stroke engines. they dont mind crusing around at partial throttle.
my experience with nitro 2 strokes is that they tend to "load up" on partial throttle settings.
for example when going around after an approach it is sometimes necessary to burp the 2 strokes to ensure they wil throttle back up.
