It’s difficult to say whether 160 parts will be available. The HH site says backorder. I just had the cam block replaced on my new 160 last week and went through three ignitions in November as well. I spoke with the mechanic that did the repairs on each occasion. He told me that the 160 is discontinued and there were no more ignitions available for replacement. He also didn’t know whether parts would be restocked for the 160. I discovered from UMS that the 160 pushrod problem has been resolved by replacing the aluminum tubes with stainless steel. The HH mechanic was not aware of that either. So, HH apparently doesn’t keep any of their people informed of what is going on with product they sale to us...I sure don’t want to deal with UMS (India) directly
