This is the saw we use for cutting both pavers and wall blocks. Most projects we are doing both. So it's nice to have a saw that's big enough to cut through SRW block but can also do 2-3" pavers. The problem we keep having is this saw is constantly having engine problems. We even changed the engine to a new Honda engine last winter and still having similar problems. After using it for a while it just doesn't want to keep idle. So then we call our small engine machanic and he does his magic on it, tell us to keep the air filter clean (which we do, twice every day when in use) and it works fine for a little while. But then within a few days of use it starts doing it again. I think the problem is related to way too much dust. But to that end, we are cleaning the filter regularly. Do we just need to purchase a higher grade of chop saw? Or what do you guys sugggest? If you think I need a new one, let me know what brand / kind you recommend. Whatever it is, I need it to be able to do block and pavers both. .
