Fixed the Fuel Tank Vent Problem on My Efco 152 Saw Today
« on: December 19, 2010, 08:49:26 PM »
Some of you may recall that I bought this 152 Efco as a open box saw a couple months ago and Solo 681 on a package deal.

The little 152 ran good for about 4 minutes with a full tank and then had a fuel flow problem. I found the pick up filter clogged and this surprised me for a new saw and just one tank of fuel through it. The real problem was a black wafer type disk that was in the fuel line and at the coupling of the tank filter... very strange.  After these repairs, the saw ran just a little longer in time and when I cracked the fuel cap, the saw ran fine. Also, one of the FF folks here pointed out and I was aware of this.. Not to run the saw like this because it would be running lean (fuel starved) when wide open WOT).

Today, I looked at the parts manual and found the fuel vent and it was in the side of the handle. I pulled the carb. and checked all the fuel lines and all that and drained the fuel out and back blew all the lines routed into the tank. With the fuel handle removed and the tank cap off,  I compressed the fuel tank with about 15 psi of air pressure. Guess what, zero air coming out of the vent in the handle in thee suck in direction.  I had a very small drill and drilled the center of the fuel vent and it twisted out in the process. I looked it over and it was as hard as rock.  I could Not move air through it. Not much of a surprise. The Vent Filter is  3/16 dia. by 1/4 long and white in color. It is a  duck bill type and a spring that fit over top of it.

I blew a little air through the vent passage way and it was Ok. I do not have a Efco dealership around here (Bonifay, FL) and did a little modification to use the saw. I drilled the vent with a very small drill through 3/4 of the length of the filter. I took and stuck a small neetle in to the sides and connected the center hole to the small needle holes. I was able to pass air throught he filter now. I did not have time to run the saw for a long period of time but started and ran Ok.

Just thougtht I'd pass this fix  along to you guy's and what I ran into with the Efco.
