Ok Gentlemen. Here's an update.... on a very positive note!
The last two weeks have seen me very busy with pastoral duties and various other things that needed to be done. In the last week, the wife and I have been over 3000 miles helping kids move from San Angelo to Marble Falls. Visiting my buddy's daughter in law in the hospital in Houston. Speaking at a family retreat at the HEB encampment in Leakey, TX. Going to visitation for my Uncle's funeral on Saturday in the DFW area and then going back on Monday for the funeral on Tuesday morning at the National Cemetery in Dallas. And various runnings and goings on in between all those things.
Couple that with the disappointment I had when I tried to get the engine running on this build and the subsequent disenchantment with the small engine parts suppliers trying to either get parts to rebuild the carb on this thing or just totally replace it, I was getting fed up with the whole process of this build. But, I've always had a tenacious spirit and was determined to make this thing work. So I poured almost a whole bottle of Sea Foam in the fuel tank along with about a half a gallon of gas and let it sit for the last week or so with the fuel valve on, hoping beyond hope that this would do the trick.
I suspected all along that it was more of a problem getting the needle set right than anything else. I'd move it one way and it'd flood the carb. Move it the other way and it wouldn't allow even one drop of gas into the carb. I pulled and re-installed that carb over three dozen times after I mounted the engine and before I let it sit. I also knew I needed a new battery. So last week we bought a battery and just set it on the frame until I could take the time to work on it again. That happened this morning.
I got up this morning determined to either make this thing run or jerk the engine off, throw it in the trash and go steal one somewhere... or rob the engine off the only running lawn tractor we have and fix the push mower so the wife could still mow the 2 acres of grass that we have fenced off as our yard.
The first thing I did was change the battery and then gave the carb a quick squirt of starting fluid and that baby fired right up and ran great. I told the wife I was going to just let it run until all the fuel was gone. That lasted about 2 minutes and then, starved for fuel, it died. Needless to say I was a little miffed. So while she ran a couple errands, I pulled the carb off again. Removed the bowl. Jacked with the needle. Re-installed the bowl. Hooked the fuel line up and just put the carb on the mounting bolts until I was sure I had the needle set right. I didn't. Pulled it all off again. Jacked with the needle. Re-installed. Turned on the fuel and watched the fuel run out the over flow. Turn fuel off and repeated this procedure at least another dozen times until I finally decided, this time is the last time. And it was. By George! I've got it running!
I let it run for about 20 minutes.. Then I killed it and greased the bearings on the jack shaft. Hooked up the oil line to the bar oil tank and set it to drip on the infeed side of the nose. (that way it will make its way around the nose before hitting resistance in the cutting side of the bar. I fired it back up and turned on the oil and let it run like that for about 5 more minutes. I am satisfied!
Now all I have to do is build the track that I was going to build three weeks ago but decided against it until I got the engine running right. I also need to install a heat shield for the battery. The hot air coming off the engine is ducted towards that side. Coupled with the exhaust manifold being there too, it is putting off a lot of heat that will surely kill a battery over time.
Here's a pic of it running and a video. I don't know why there isn't any sound. But pay attention to the last few seconds as I hit the clutch engage switch and the chain starts spinning.
PS - forget the video. I forgot I have to add it to youtube and then add the link here. Ain't nobody got time for that! That and I don't remember my youtube password.
