I'm looking for some advise on mounting my first gas engine. The project is an AW 29% Edge with a BME 50. Now when I ordered the engine, I asked the salesman for his suggestions on an engine mount and I ended up with a DuBro 1.20 size soft mount. I have one of these on a GP extra with an OS 1.20 4-stroke and it made a world of difference. So I went ahead and used it (as you can see in the picture I had a machinist friend make some standoffs to get the spacing). Anyway, I hooked everything up and ran the engine. Now I know gas engines are a little shaky, but it seems a little excessive. I've read some of the other posts and it seems that everyone has their engine "hard mounted" and there is some discussion on using standoffs or using ply spacers. So finally my question is, does it look ok or should I do some reworking?

bdphil,
When I first read your post my first thought was, the engine is too rich. Out of the box, I thought my ZDZ 80 was having a seizure the first time it ran. The low needle is supposed to be set at 1.5 turns from stop it was 4 turns out. I reset the needle to factory specs and the engine ran great. As long as everything is tight on your install it should work fine. Readjust the engine and try running it somemore. Let us know what happens.

The inserts in that soft mount are going to wear out quickly, so have some on hand, or hard mount the engine.

I agree with Jemo, I would hard mount the engine. I did not realize when I looked at the pic that those were soft mounts, hard to tell what they were.

Thanks guys. I hoping that I wouldn't have to redo everything. It is a Dubro 120 size soft mount, but I think i'll leave it and see how long the bushings hold up. If it tears them up too fast, I'll hard mount it. I've run the engine a couple more times and it seems to be smoothing out a bit (I had to lean the low needle some).

One other question that I had, There is some black sticky crud spattering out of the exhaust. I read in another post that this can be expected for the first gallon or so. Sound normal? I'm new to gas engines and I want to try not to make any wrong moves. I'm using the recommended break in mix of 87 octane and lawn boy ashless oil at 32:1.
